Non-technical AbstractThe molecular spins have a high potential of being used in future micron-scale devices dealing with either classical or quantum aspects of information technology. Recently it has been shown that "man-made" spins can behave quantum mechanically under specific conditions. The goal of this Faculty Early Career Development (CAREER) project at the Florida State University is to investigate the quantum dynamics of molecular spins coupled strongly to resonant photons, with an eye on potential implementations in the information technology field. Spin detection will be accomplished by coupling the spin to an electro-magnetic field inside specially designed microscopic cavities. Achieving single spin sensitivity is an important objective, together with the understanding of decoherence mechanisms in molecular samples. Through association with the NHMFL a broad condensed matter community will interact closely with the proposed research. The specifics of the research will be benefic for the training of undergraduate and graduate students and part of the techniques will be integrated in a graduate course on experimental methods in physics. The program will sustain a recent NHMFL initiative to develop a nation-wide network called SuperNet which will provide high-schools with physics demonstration modules.Technical AbstractThe goal of this Faculty Early Career Development (CAREER) project at the Florida State University is to investigate the quantum dynamics of molecular spins coupled strongly to resonant photons. Fundamental questions related to quantum macroscopicity or decoherence are at hand in these samples. Potential implementations in the information technology field will be investigated as well. In particular, the study will focus on: i) quantum non-demolition observation of an ensemble of spins, ii) observation of exotic multi-photon anti-resonances in quasi-harmonic spin states and iii) single spin sensitivity. These goals have important scientific significance and will bring light to the quantum dynamics of spins in the presence of a given environment. It is proposed to couple the total spin of a molecule to the B-component of a resonant electro-magnetic field inside microscopic cavities similar to the case of resonant cavities electrically coupled to atoms or superconducting qubits. Through association with the NHMFL a broad condensed matter community will interact closely with the proposed research. The specifics of the research will be benefic for the training of undergraduate and graduate students and part of the techniques will be integrated in a graduate course on experimental methods in physics. The program will sustain a recent NHMFL initiative to develop a nation-wide network called SuperNet which will provide high-schools with physics demonstration modules.

分子自旋在未来处理信息技术的经典或量子方面的微米级器件中具有很高的潜力。最近的研究表明，“人造”自旋可以在特定条件下表现出量子力学行为。佛罗里达州立大学的这个教师早期职业发展（CAREER）项目的目标是研究分子自旋与共振光子强耦合的量子动力学，着眼于信息技术领域的潜在实现。自旋检测将通过将自旋耦合到特殊设计的微观腔体内的电磁场来实现。实现单自旋灵敏度是一个重要的目标，连同分子样品中的退相干机制的理解。通过与NHMFL的联系，广泛的凝聚态物质社区将与拟议的研究密切互动。研究的具体内容将有利于本科生和研究生的培养，部分技术将被整合到物理实验方法的研究生课程中。该计划将维持最近的NHMFL倡议，开发一个全国性的网络称为SuperNet，这将提供高中物理演示modules.Technical AbstractThe的目标，这教师早期职业发展（CAREER）项目在佛罗里达州立大学是调查的量子动力学的分子自旋耦合强烈的共振光子。在这些样本中，与量子宏观性或退相干相关的基本问题就在眼前。还将调查信息技术领域的可能实施情况。特别是，该研究将侧重于：i）自旋系综的量子非破坏观测，ii）准谐波自旋态中奇异多光子反共振的观测和iii）单自旋灵敏度。这些目标具有重要的科学意义，并将在给定环境下为自旋的量子动力学带来光明。提出了将分子的总自旋耦合到微观腔内的谐振电磁场的B分量，类似于谐振腔电耦合到原子或超导量子比特的情况。通过与NHMFL的联系，广泛的凝聚态物质社区将与拟议的研究密切互动。研究的具体内容将有利于本科生和研究生的培养，部分技术将被整合到物理实验方法的研究生课程中。该计划将支持NHMFL最近的一项倡议，即开发一个名为SuperNet的全国性网络，该网络将为高中提供物理演示模块。
